Understanding and Calibration of Charge Storage Mechanism in Cyclic Voltammetry Curves
Angewandte Chemie - International Edition, 2021AbstractNoticeable pseudo‐capacitance behavior out of charge storage mechanism (CSM) has attracted intensive studies because it can provide both high energy density and large output power. Although cyclic voltammetry is recognized as the feasible electrochemical technique to determine it quantitatively in the previous works, the results are inferior ...

Revealing the Charge Storage Mechanism of Nickel Oxide Electrochromic Supercapacitors
ACS Applied Materials & Interfaces, 2020Nickel oxide (NiO) is considered one of the most promising positive anode materials for electrochromic supercapacitors. Nevertheless, a detailed mechanism of the electrochromic and energy storage process has yet to be unraveled. In this research, the charge storage mechanism of a NiO electrochromic electrode was investigated by combining the in-depth ...

Charge storage mechanism of copper hexacyanoferrate nanocubes for supercapacitors
Chinese Chemical Letters, 2020Abstract The widely accepted theory concerning the electrochemical energy storage mechanism of copper hexacyanoferrate (CuHCF) for supercapacitors is that CuHCF stores charge by the reversible redox processes of Fe3+/Fe2+ couple and Cu cations are electrochemically inactive. In this work, CuHCF nanocubes (CuHCF-NC) were synthesized in the presence of

Charge Storage Mechanisms of Carbides and Nitrides
ECS Meeting Abstracts, 2015Introduction Early transition-metal carbides and nitrides are potential electrode materials for supercapacitor applications due to their high accessible surface areas, high electric conductivities and low cost. They possess high capacitances, good capacitance retention during cycling and wide voltage windows.

Charge storage in SnO2 nanoparticles: A method and mechanism for charge writing/erasing
Applied Physics Letters, 2007In this work, we present and explain evidence of a charge confinement phenomena exhibited by SnO2 nanoparticles. By applying a voltage pulse from the scanning tunneling microscope (STM) tip or momentarily increasing the gap voltage, charged features can be written on the surface.

A New Charge Storage Mechanism for Electrochemical Capacitors
Journal of The Electrochemical Society, 1995The hydrous form of ruthenium oxide (RuO[sub 2][center dot]xH[sub 2]O) has been demonstrated to be an excellent electrode material for electrochemical capacitors. This material, as prepared by a sol-gel process at low temperatures, is amorphous and electrically conductive. The specific capacitance is over 720 F/g.

Local charge storage and decay mechanism in silica
SPIE Proceedings, 2009Positive and negative charges are stored locally in thin films of silicon oxide on silicon by applying a voltage between an AFM cantilever tip and the silicon substrate. The stored charges are displayed by Kelvin probe force microscopy (KPFM). The process of charge storing is investigated with respect to different dwell times and different voltages ...
